Biological treatment method of river pollution with strong redox

Abstract

The invention discloses a strong-redox biological treatment method for river pollution. The method comprises the steps of adding redox treating agent into river wastewater, starting an aeration fan, directly injecting microbubbles into the river wastewater and obtaining pretreatment fluid after treatment, wherein the redox treating agent is prepared from polyacrylamide, amphoteric starch, phosphoric acid, tannic acid, ferric oxide, aluminum sulfate, deionized water and polymerization ferric chloride; arranging the pretreatment fluid into a moving-bed bio-membrane reactor to be treated, then evenly spraying on a biodegradation bed to be treated in a biodegradation mode, finishing biodegradation when wastewater passes through bio-enzyme treating agent and filtering to obtain clean water, wherein the bio-enzyme treating agent is prepared from oxidation-reduction enzyme, cellulase, biological flocculant, chlorella, zoogloea, kieselguhr, sodium gluconate, montmorillonite powder and the like. The strong-redox biological treatment method can effectively remove most pollutant in river wastewater and further has the advantages of high efficiency, environment friendliness and no secondary pollution to environment.

Description

technical field

[0001] The invention relates to the technical field of sewage treatment, in particular to a strong oxidation-reduction biological treatment method for river pollution. Background technique

[0002] With the rapid development of China's economy and the rapid growth of urban population, the rain and sewage diversion pipe network is not perfect, the construction of urban sewage treatment plants is lagging behind and the start-up is insufficient, and the amount of sewage treatment and sewage discharge is seriously out of balance. The sewage flowing into the river will inevitably pollute the river. It causes the river water to become black and smelly, seriously affecting people's lives, even endangering human survival, and posing a serious threat to the health of urban residents and urban ecological security. According to surveys, nearly 50% of the 700 important rivers in China, and more than 90% of the waters along the rivers have been polluted. The dissolved ox...
